About Rspamd
Rspamd is rebuilding its neural filter into a pluggable framework — and just fixed a controller that accepted any password.
The 4.1.x series has moved fast on two fronts. The neural plugin gained pluggable feature-provider and ANN-architecture registries, multi-head attention pooling, slice and concat graph transforms, and a static_embed provider running a WordPiece subword tokenizer over a static embedding matrix. Separately the fuzzy subsystem got structured match results with a diagnostics API, Redis-persisted shingle sets and per-hash introspection. 4.1.4 in July fixed a critical controller bug where a malformed password hash caused it to fail open and accept any password, alongside a set of PCRE2 leaks and unbounded-match conditions in the regexp engine.
